https://www.pexpeppers.com/ They accept STEEM via Coinpayments.
Haven't purchased anything from them but basically any website can accept STEEM Payments using Shopping Cart Plugins created by CoinPayments.
Check this directory of stores using their plugins: https://cryptwerk.com/companies/?f[27]=99
Chances are, some of these are accepting STEEM too. ;) And if they are not accepting it yet, let's make them an account!!! And ask them to use STEEM as well.
Please post this info on Twitter if you don't mind. :)
Sure. I will do it Dan ;) Cheers!
